1. Overview 1.1 This test method includes methods for evaluating the tensile properties of vulcanized thermosetting rubber and thermoplastic elastomers. This test method can not be used to test hard glue and materials with high hardness and low elongation. The test method is as follows: Method A -- Straight bar and dumbbell...
1 Range This standard specifies test methods for electroplating of silver and silver alloys for engineering, decoration and protection purposes against contamination by residual salts. This standard applies to metal parts; Not applicable to composite parts, such as parts with both plastic and coated metal. 2 Principle The part was boiled in water with...

Introduction ISO (International Organization for Standardization) is a global federation of national standards bodies (ISO member bodies). The development of international standards is usually carried out through ISO technical committees. Each member group interested in a subject on which a technical committee has been established has the right to be represented...
1 Range This STANDARD specifies the technical REQUIREMENTS AND test methods for electroplating of Tin-lead alloys with tin content ranging from 50% to 70%(mass ratio) (see 10.3). This standard applies to electroplating of tin-lead alloys to prevent corrosion and improve soldering properties on electronic, electrical and other metal products. This standard also applies...
Meaning and Use 3.1 Since the pipe coating is subject to concentrated pressure exerted by the weight of the pipe and the backfill, this test is mainly used to determine the resistance of the coating to penetration or deformation under controlled conditions. 3.1.1 If the coating is not penetrated, the deformation of...
Meaning and Purpose 4.1 The test will provide information about the ability of the coating applied to the pipe to resist cracking, peeling or other mechanical damage caused by bending. Since the test is applicable to commercially produced coated pipes, the results can be directly used to select similar service materials....
Scope of 1.1 This test method includes an accelerated procedure for simultaneously determining the comparative characteristics of the insulating coating system applied to the exterior of the steel pipe with the purpose of preventing or mitigating corrosion that may occur in underground service where the pipe will come into contact with...
